(Cl. 21o-131) 14 Claims.

This invention relates to filters and more particularly to thecartridge-type filter usedin lubrication systems of internalcombustionengines. This type of filter is characterized by a sealedcontainer having threaded openings into which are screwed fittings foreffecting attachment of the cartridge to the ends of two pipes throughwhich dirty oil is supplied to and clean oil is discharged from thelter. Each engine manufacturer has its own arrangement of pipes and somearrangements require inlet and outlet openings at the saine end of thecartridge While other arrangements require the inlet opening at one endand the outlet opening at'the otherl end. Y

An object of this invention is a cartridge-type tion I9 rof each endwall ofthe container.V The filter of such construction and arrangementthat it may be easily connected up to either of the two above-describedpipe arrangements.

Other objects, novel features and advantages of this invention willbecome apparent from the following specification and accompanyingdrawing, wherein:

. Fig., 1 is a sectional view of a filter embodying the invention;

Fig. 2 is a section on the line 2-2 of Fig. 1;

, Fig. 5 illustrates a modification.

The cartridge housing or casing I0 consists of two cup-shaped partshaving their rims interjoined at II to form a permanent seal. The endsof the casing are slightly offset and in one offset is arranged areinforcing block I2 and in the other offset is arranged a reinforcingblock I3. The block I2 is substantiallycircular and is provided with acentral passageway consisting of a threaded bore I4 terminating in aprojection I 2a extending inwardly from the block I2. The block I3 is ofelongated contour and has a port consisting of a threaded bore I5, theaxis of which is in alignment with the axis of the bore I4. Also, theblock I3 is provided with a passageway consisting of a threaded bore I6terminating in a projection I3a. extending inwardly from the face of theblock, the bore I6 being offset from the bore I5. The casing I0 isprovided with apertures registering with the bores I4, I5 and I6.topermit the flow of voil into and out of the housing. A filtering unit isarranged Within the casing and comprises a cylindrical metal containerII having an imperforate side wall and perforate end Walls. A tube I8extends lengthwise of the container and each end of the tube receives aninwardly ofsetpor-v tube I8 is surrounded by a body of filteringmaterial I8a and a distributor 2li carried by the tube I8 projects intosaid body `offiltering Ina-y terial. In each offset end portion I9 isprovided an orifice 2I. through which oilmay ojwinto the tube I8 andsaid tube is provided with one or more apertures 22 through which oilmay flow from the tube into the distributor fromV` which it may escapeby way of holes 23 into the body Y of filtering material. vA flangedplate 24 hasits ange 24a presstted on the block I3 to form a chamber 25and` has a depression receiving the" projection I3a. The depression isprovided with, a collar 24h which extends into the projection I 3a. Asecond angednplate 26'has its flange 26a presseY fitted 'on the ange 24aand the two plates .cooperate to form a chamber 2l communicating withthe bore or port I6. The plate 26 has an offset Vportion 28fittingintothe recess in theV remaining end wall of the container I1 andalso has an orifice 28a in register with the orice 2|. The plate 2871scomposed of resilient metal and the arrangementV is such thatitVprovides sufficient resiliency to establishxliquid tight seal lbetweenthe ends of the container and the projection' I`2a andthe offset portion28. The plate 'y 24 is provided' with offsets 29 for engagement with theblockA I3 to maintain the plate in spacedrelation thereto and forengagement by the plate-126 to prevent collapseof the plate 26 towardthe plate 24. Aligned' cutouts are pro.- vided in the flanges 24a and26a to provide a port 33 establishing communication between` the chamber25 and the interior of the casing I0.

The plate 28has an annular offsetv 3|, centrally of which is an offset32, and in the space between V thetwo offsets are providedholes 33..A'rivet 34 passing through the offset 32 is attached to a resilient disk35 which rests in liquid tight relation thereto.

The'boresrl4 and I6 constitute inlet ports while the bore I5 constitutesan outlet port. Y When installed, the. dirty oil `pipeV communicateswith either the bore I4 or the bore I6 and the remaining bore is pluggedand in Lall installations the clean oil pipe communicates with the borel5. When dirty oil is suppliedthrough I8 by wayv `the bore I4, itpassesintothe tube of the orifice 2I and then ows through thedistributor 20 into the lbody of filtering material. When dirty oil issupplied through the bore I6, it passes into the chamber 2l and fromsuch chamber through the orifices 28aV` and 2l on `the yoffset 3|Vchamber into the .casing through the holes 33 a. single inlet in thesame endfwith theQoutlet,

Filtered oil surrounds the element l1 andescapes from the interior of the casing I 0 through the port 30 in`tothe chamber- 25 from Y. which it ilows out through the discharge port I5.
